Optimal time-invariant operation of a power and water cogeneration solar-thermal plant

►A cogeneration of power and water suitable for concentrated solar power is proposed. ► Optimization of cogeneration operation results in significant improvements of savings. ► A system-level model for power generation and hybrid desalination is proposed and validated. ► Thermal desalination is only promising if advances in its performance are made. ► The current incentives for renewable electricity and power do not favor desalination.
